Phillip Quinlan Posted July 25, 2013 Report Share Posted July 25, 2013 Hi guys I have a lem v3 and have had it just wired up to my 4agze engine but running a turbo not the s/c. im using the standard cas and standard dual post coils for a waste spark setup with a link 2 channel ignitor. Â I have been tryning to get this to start up at the start i was running a subaru ignitor but it got hot while cranking over and lost one of its output channels. i hav since got a link ignitor but same thing is getting hot while cranking. its got spark so its trying to fire but with no luck of getting it to idle. the heating up issue was wondering if it could be a dwell setting?? if so am having trouble finding this on the hand controller? my ecu is a d42v3 was told it was running on a 4age turbo before i got it. will supply picture of internals attached for you. any help would be much appreciated. Cheers phil. Quote Link to comment Share on other sites More sharing options...
Simon Posted July 26, 2013 Report Share Posted July 26, 2013 The reason is that the V3 is only geared for distributor applications and as such the Ign2 drive is for honda igniters and is an inverted signal. This will cause your igniter and coil to cook themselves. To make this work for wasted spark you need a upgrade to V5. Quote Link to comment Share on other sites More sharing options...
Phillip Quinlan Posted July 27, 2013 Author Report Share Posted July 27, 2013 Ohh really yeah well that would do it. Â Will look into an upgrade. Cheers simon Quote Link to comment Share on other sites More sharing options...
Phillip Quinlan Posted February 4, 2015 Author Report Share Posted February 4, 2015 Hi Simon still working on this same project believe it or not, i now have a version 5 but having issues once again its got spark but struggles to fire, it seems like the timing could be way out however i have set the base timing by changing the advanced limit to zero then setting it to 10degrees with the light. here is my pcl file attached and also some pictures of inside the link. any tips would be much appreciated, cheers Quote Link to comment Share on other sites More sharing options...

Simon Posted February 4, 2015 Report Share Posted February 4, 2015 In the CAS do you have the 24 tooth pickup or is it using a tooth per TDC? In the ECU does the sub-board have a chip with a sticker on it with SUB24NEW or similar. Need to make sure you have the correct sub-board other wise the RPM reading will be massively out and with that the spark events too.

Phillip Quinlan Posted February 5, 2015 Author Report Share Posted February 5, 2015 The cas has the 24 tooth wheel and a single on top of that, the main chip is d42v5e071205 and I have taken another picture of the smaller board on top for you should be attached , cheers Quote Link to comment Share on other sites More sharing options...
Phillip Quinlan Posted February 5, 2015 Author Report Share Posted February 5, 2015 Also I am not using air temp or oxy sensor could this be a issue? Quote Link to comment Share on other sites More sharing options...
Phillip Quinlan Posted February 5, 2015 Author Report Share Posted February 5, 2015 Just noticed as soon as it tries to run the ignition advance goes right up to the limit which I hav set at 25 Quote Link to comment Share on other sites More sharing options...
Phillip Quinlan Posted February 5, 2015 Author Report Share Posted February 5, 2015 One other possibility the main board has the row of 4 dip switches what should these be set to? Could possibly hav something to do with ignition timing? Quote Link to comment Share on other sites More sharing options...
Scott Posted February 10, 2015 Report Share Posted February 10, 2015 Hi Phillip, Simon is away this week, so is unable to answer your questions. He is the guru with these G1 ECUs. I will have him reply upon his return. Scott Quote Link to comment Share on other sites More sharing options...
Simon Posted February 18, 2015 Report Share Posted February 18, 2015 Main issue with the ECU as it is now is the sub-board is not correct for the 24 tooth trigger. It is a basic Reluctor board that requires a tooth for each TDC and a single sync. Currently the RPM reading will be 6 times too high. Â Only solution will be to modify the CAS to leave 4 teeth at TDC points. We no longer have any of the required sub-board to allow the 24 tooth input.

Phillip Quinlan Posted February 18, 2015 Author Report Share Posted February 18, 2015 Oh bugger that's no good then so if I take the other 20teeth off the 24tooth wheel that should be able to get it to run with the dual post coils? And leave the single tooth rotor alone? what should I have priority set to with this setup? Quote Link to comment Share on other sites More sharing options...
Simon Posted February 18, 2015 Report Share Posted February 18, 2015 Yep that will allow dual coils. you can set the priority to cyl. Quote Link to comment Share on other sites More sharing options...
Phillip Quinlan Posted February 18, 2015 Author Report Share Posted February 18, 2015 Awesome thanks Simon will let you know how I get on Quote Link to comment Share on other sites More sharing options...
